When a commercial building is designed, the emphasis is always on profitability, and value. The building needs to be designed in a way that facilitates the efficient performance of the business, while at the same time is constructed for long use with low maintenance. Very rarely is the overall aesthetic a priority, but attractive buildings are desirable and that is taken into consideration. The heart of any wide and low structure is the roof. It is usually the single most important structure for the building. There are 5 common materials used for roofing on commercial buildings.
- Metal Roofing: Metal roofing is the gold standard for sloped roofs because it has numerous advantages. It is competitively priced, it installs easily, it is very long lasting, it is durable, and it is attractive, coming in a range of colours. Another aspect of metal roofing is that it is recyclable. You can find commercial metal roofing in Perth from established commercial roofing contractors. Metal roofing is not designed for load bearing, and it is not suitable for flat roof designs.
- Single-Ply Membrane Roofing: This method of roofing is more a watertight protection for a roof and is not necessarily structural. In this process, rubber or other synthetic sheeting is stretched across an insulated surface and fastened either with adhesives or mechanically.
- Spray Polyurethane Foam Roofing: SPF is applied as a spray on coating. This process can be applied to any shape of structure. It provides a moisture barrier and good insulation. It is surprisingly durable, lasting up to 50 years. This is a very light material, and some versions are quite ecofriendly.
- Shingles: Shingles are an ancient building technique that has been advanced and adapted as technology has advanced. Shingles come in a few different materials, most commonly asphalt for commercial applications. As other materials like slate and wood require more work and increase the cost without increasing the effectiveness. Shingles are intended for sloped roofs only.
- Built-Up Roofing: Built up roofing is very common for wide roofs with little or no slope, Built-up roofing is created by applying several layers of tar and fabric and then is topped with a layer of aggregate. Built-up roofing is seamless and waterproof, but it does require maintenance occasionally. It is also a heavy roofing material.
